MAXIMUM-CAPACITY RAILWAY CAR.

Application filed January 3-, 1922.

T 0 all whom it may concern:

Be it known that I, DAVID HINDAHL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Maximum-Capacity Railway Cars, of which the following is a specification.

This invention relates to railway cars of that type in which a wall of the car is formed partly in one plane and partly in will place a much greater proportion of the confines of the car in the extreme permissible position than in constructions heretofore proposed, and bring the offset or shoulder which unites the two portions of the car wall closer and therefore in better protective relation to the ladder.

Another object is to so construct a car of the type described that the offsetting portion of the wall can enter into direct relation with the ladder and become an element of security therein, besides simplifying and cheapening the construction by doing away with the use of vertical stiles for spacing and sustaining the rungs of the ladder.

In order that the invention may be fully understood, the preferred embodiment thereof has been illustrated in the accompanying drawings, and will be set forth in detail in the following description.

In said drawings Figure 1 is an end elevation of a railway car in which the several features of the invention are embodied.

Figure 2 is a side elevation of the portion of the same which is immediately concerned with the present invention; and

Figure 3 is a plan view partly in horizontal section in a plane immediately above one of the rungs'of the ladder.

10 represents the side wall of a car which is sustained by internal side stakes 11, one of which is shown in a manner to permit the main area of the wall to occupy the extreme permissible outside position and thereby in- Serial .No. 526,547.

crease the capacity of the car. Side wall 10 is provided with recess 12 which substantially corresponds in width to the width of a ladder 13 which is located therein,and it may also with advantage be made to correspond in depth with the thickness of the ladder and in height with the ladders length. By making the recess substantially equal to that of the ladder, the offsetting shoulder, which develops the recess, will be brought into such close proximity to the ladder as to greatly enhance the protection of the ladder against a side wipe which the car may encounter. Moreover, this offset is preferably developed through the medium of an angle iron 12 havin inner flange 12 which lies substantially in t e plane of the-inwardly offset portion of the wall, and an outer flange 12 which lies in the plane of the more remotely located main area of the wall; and'this angle iron becomes the means of directly supporting the ladder 13 and permitting the rungs of the ladder to be riveted, bolted, or otherwise secured without .the interposition of a vertical stile or other member.

Recess 12 is preferably located at the end of the wall in which it is formed, and therefore has one of its confines determined by the angle iron 12 which reinforces the corner of the car. and this reinforcing corner member thus affords support for the other ends of the ladder rungs directly and without the interposition of a vertical stile. In other words, the offsetting angle iron 12 is spaced from the reinforcing corner iron 12 a distance corresponding substantially to the width of the ladder, with the result that not only is the ladder more cheaply and more securely sustained within the overall dimensions of the car, but the area of that portion of the wall 10 which occupies the position of maximum dimension and enlargesthe capacity of theQcar, extends so near to the end of the car, that the construction constitutes a substantial improvement and means for realizing the principle of maximum capacity I .connecting said portions of said Wall, and

ladder rungs overlying, said inwardly offset portion of the wall and secured to said reinforcing member.

3. A plate metal car having a corner member, an offset member in substantially the same plane with said corner member and spaced therefrom a distance corresponding substantially to the width of a ladder, a ladder secured to said corner and offset members, and a wall extending from said offset member in a plane substantially parallel with but more remote from the interior of the car and the plane of said corner and offset members.

4. In a plate metal car, a reinforcing corner member, an angle iron spaeedfrom said corner member a distance corresponding substantially to the width of a ladder and having inner and outer flanges lying, respectively, in a plane with a portion of said corner member and in a parallel plane outwardly offset therefrom, a ladder supported by said corner member and said inner flange, and a wall plate supported by said outer flange.
